- How to Make a Blood Smear STEP ONE: Place clean glass slide on a flat surface. Add one small drop of blood to one end. STEP TWO: Take another clean slide, and holding at an angle of about 45 deg, touch the blood with one end of the slide so the blood runs along the edge of the slide by capillary action. Push carefully along the length of the first slide to produce a thin smear of blood. STEP THREE: Make 2 smears, allow to air dry, and label clearly. Once dried place in the provided slide transport containers.

- How you prepare. If your blood sample is being tested only for a complete blood count, you can eat and drink normally before the test. If your blood sample will be used for additional tests, you may need to fast for a certain amount of time before the test.Your doctor will give you specific instructions.f your blood sample is being tested only for a complete blood count, you can eat and drink normally before the test.

LAB 6: GRAM STAIN AND CAPSULE STAIN First place a small piece of tape at one end of the slide and label it with the name of the bacterium you will be placing on that slide. 2. Using the dropper bottle of deionized water found in your staining rack, place 1/2 of a normal sized drop of water on a clean slide by touching the dropper to the slide (see Fig. 1). Altenately, use your sterilized inoculating loop to place a drop of deionized water on the slide.

- ORDER OF DRAW. Blood collection tubes must be drawn in a specific order to avoid cross-contamination of additives between tubes. The recommended order of draw for plastic vacutainer tubes is: First - blood culture bottle or tube (yellow or yellow-black top) Second - coagulation tube (light blue top). If just a routine coagulation assay is the only test ordered, then a single light blue top tube may be drawn. If there is a concern regarding contamination by tissue fluids or thromboplastins, then one may draw a non-additive tube first, and then the light blue top tube.

- Labeling of the slide(s) is not necessary since the slide(s) will be read immediately following. preparation. Wet mounts of vaginal discharge may be prepared using either the direct (saline or KOH. added directly to discharge on slide) or indirect (discharge added to saline in tube then.

- If you have two cover glasses stuck together you will not be able to use the 100x objective on your specimen. Collect Data. (. Examine the wet mount slide of Elodea, first using the 4x, objective, then with the 10x, and then the 40x.rocedure. (. Prepare a wet mount of your cheek cells: 1. Put a drop of water on a slide. 2. Gently scrape the inside of your cheek with the flat side of a toothpick. Scrape lightly. 3. Stir the end of the toothpick into the water and throw the toothpick away. 4. Place a coverslip onto the slide.

- 12. With a dropper, place a small amount of water on a clean slide. Place a leaf of the water plant Elodea on the slide in the drop of water. Place the edge of a cover slip at the edge of the drop and lower the cover slip slowly to the slide surface. With care you can prepare a wet-mount with few if any air bubbles.13.ever remove a slide with the high-power or oil immersion objective in place as you might scrape the lens of the objective. 5. Place a slide of diatoms, microscopic organisms from both marine and fresh water environments, on your microscope.

- Step 1: ®Remove Assure Platinum Test Strip from the bottle. Immediately replace the bottle cap tightly. Insert test strip as shown in the diagram. Meter will turn on automatically. Verify that all symbols appear on the screen. The strip and flashing blood drop indicate the meter is ready for use. Step 2: Obtain a blood sample. Touch the sample application tip at the end. of the strip to the blood drop on your finger. Capillary action will pull. the blood into the strip.

hypernatremia Blood plasma and serum — Blood plasma, or plasma, is prepared by obtaining a sample of blood and removing the blood cells. The red blood cells and white blood cells are removed by spinning with a centrifuge.

Drawing blood for ABGs Once you've settled on a site, you can prepare for the blood draw. First, fill a clean plastic bag, paper cup, or emesis basin with ice. You will use it to transport the sample to the lab after it's drawn.

- Steps 1-3 – Check, Explain, Wash 1. Identify the patient by checking the arm band or area-specific procedure.2. Explain the procedure to the patient.3. Wash hands with soap and water with friction for 15 seconds or use alcohol based hand rub. Step 4 – Prep Cap 4. Prep the rubber cap of the blood culture bottles with an alcohol pad in a circular motion. Allow the alcohol to dry.

smear The slide is dried by waving it in the air; it should not be heated. The blood smear is covered with Wright's stain and allowed to stand 2 min. An equal amount of distilled water or buffer solution is added and mixed uniformly. It is allowed to stand 5 min. The stain is gently washed off and the slide is allowed to dry.

CBC with Automated DifferentialTest Code:    HGMPA Collection Processing. Invert specimen at least 5-6 times in order to facilitate mixing and prevent coagulation. Prepare blood smear as soon as possible, preferably within two hours of collection, up to 24 hours, label with computer generated label or use pencil to label with patient's full name and date. Store slides at room temperature.​.

- The previously transparent Gram-negative cells will take up the safranin and appear red. Step 8: Gently rinse with water as before. Step 9: Gently blot dry the slide. At this point, ordinary paper towels or special tablets of blotting paper are used to gently blot off the excess stain and water. Never rub dry the slide.

- But for this stain you will add two samples to the slide .Place the samples in distinct locations on the slide. The samples should not mix or overlap. The first sample will be a Gram stain control culture and the second sample will beyour test sample. After air drying, heat fix the slide.6. Place slide in staining tray, flood with crystal violet.

Insulin Test Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding. In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.

- Blood Collection Tubes Complete Blood Count (CBC): EDTA tubes (purple top): Purple top tubes should be 50-60% full. Do not overfill tubes. Gently mix specimen by inverting 5-10 times and place it on a rocker for up to 30 minutes, then refrigerate at 2-8°C. When a differential is required as part of a CBC, slides must be prepared within 12 hours of blood collection. Refrigerated EDTA blood is stable for CBC for up to 24 hours.

- Doctors use thick and thin blood smears to determine whether you have malaria. If one test is negative and no parasites are found, you will have repeated blood smears every 8 hours for a couple of days to confirm that there is no malaria infection.Blood smears are taken most often from a finger prick.Thick and thin blood smears will let doctors know the percentage of red blood cells that are infected (parasite density) and what type of parasites are present. 1  A thick blood smear is a drop of blood on a glass slide.2  A thin blood smear is a drop of blood that is spread across a large area of the slide. (Often there are few parasites in the blood at the time the test is done.). 2  A thin blood smear is a drop of blood that is spread across a large area of the slide. 3  Thin blood smears helps doctors discover what species of malaria is causing the infection.

- Spread the collected fluid that adheres to the swab over microscope slide and nitrazine paper. Apply a thin layer to the microscope slide for best results. Allow slide to air dry (do not apply coverslip). Only handle slide with gloves, as fingerprints may give false results or interfere with interpretation.

SERUM, PLASMA OR WHOLE BLOOD COLLECTION SERUM, PLASMA OR WHOLE BLOOD COLLECTION. Draw blood in the color-coded Vacutainer® tube indicated in the alphabetical test listing. For serum or plasma, draw approximately 2 1/2 times the requested volume. For serum, allow the blood to clot sixty minutes and separate by centrifugation.

- 1 Most blood is spun in centrifuges to separate the transfusable components – red cells, platelets, and plasma. 2  The primary components like plasma, can be further manufactured into components such as cryoprecipitate. 3  Red cells are then leuko-reduced. 4  Single donor platelets are leukoreduced and bacterially tested.
